Compared with the patients in the control group, those in the high AS group were older (p = 0.001), had longer PD vintage (p = 0.024), and had higher serum levels of CRP (p = 0.005) and OPN (p < 0.001), but had a similar proportion of men and women, PD model, BMI, frequency of coexisting DM and HTN, adequacy of dialysis, and medications used, including the usage of calcium carbonate, calcitriol, and Icodextrin. The gene discussed is CRP; the disease is hypertensive disorder.
